Answer:
It conducts electricity
It conducts heat
Water is needed for rusting
Explanation:
Metals refer to elements that are found towards the left hand side of the periodic table of elements. They are found in groups 1- 13 and few of them are also found at the bottom of groups 14 and 15.
Now these metal have certain properties that are general to all of them. two of these properties listed among the options in the question are;
i) They conduct electricity
ii) They conduct heat
These properties apply to all metals universally.
Rusting is an electrochemical reaction in which hydrated iron III oxide is formed. In the electrochemical reaction, water in intimately involved in the process. Hence; oxygen and water are required for rusting to take place.
The answer is [OH⁻] = 1 x 10⁻⁸.
To find OH⁻, divide the ionic product of water by [H₃O⁺] as :
<u>OH⁻ + H₃O⁺ = H₂O</u>
<u />
- [OH⁻] = 1 x 10⁻¹⁴ / 1 x 10⁻⁶
- [OH⁻] = 1 x 10⁻⁸

A mixture of metals and non-metals
In this exercise, it is necessary to know the systems that our bodies have and complete the sheet that will correspond to these answers:
1- Digestive
2- Urinary
3- Respiratory
4- Skeletal
5- Muscular
6- Integumentary
7- Cardiovascular
8- Endocrine
9- Nervous
10- Reproductive
So looking in more detail, the number one corresponds to the digestive system because it is the digestive process that starts in the mouth. The second is related to the urinary system, which is responsible for the filtration and elimination of excess water. The respiratory system corresponds to the third option, which is the gas exchange that occurs in the pulmonary alveoli.
The numbers 4, 5, and 6 are very important systems for the support of the human body, being respectively the skeleton system, the muscular system, and the integumentary system. The first system is responsible for support while the second is better known for locomotion and finally the third is known for covering the human body by the dermis.
The cardiovascular system is responsible for getting the blood transported throughout the body and pumped by the heart, so this system is related to number 7. Then the endocrine system is responsible for the hormones and how these hormones acted in the body and are number 8.
The number 9 corresponds to one of the most complex and principal systems, the nervous system, which has neurons as its cells and transmits the nervous impulse in response.
The last treated system is the reproductive system, known for its reproductive gametes, and its most important role is to maintain the reproduction of the species.
